A block is lying static on the floor. The maximum value of static fictional force on the block is 10 N. If a horizontal force of 6 N is applied to the block,what will be the frictional force on the block?

Options

A. 2 N
B. 18 N
C. 6 N
D. 10 N

Answer

To solve the problem, we need to analyze the forces acting on the block and the nature of static friction.

### Step-by-Step Solution:

1. **Understanding Static Friction**:
- Static friction is the force that keeps an object at rest when a force is applied. It has a maximum value, which in this case is given as 10 N.

2. **Applied Force**:
- A horizontal force of 6 N is applied to the block.

3. **Comparison of Forces**:
- Since the applied force (6 N) is less than the maximum static frictional force (10 N), the block will not move.

4. **Determining the Frictional Force**:
- The static frictional force will adjust itself to match the applied force as long as it does not exceed its maximum value. Therefore, the static frictional force will be equal to the applied force of 6 N.

5. **Conclusion**:
- The frictional force acting on the block is 6 N.

### Final Answer:
The frictional force on the block is **6 N**.
